Of course I bought a smartphone with powerful processors just to limit their performance for the sake of delaying the expiry of its non-replaceable battery.

So you want me to artificially halve my useable battery capacity just so its actual capacity reduces slower?

That's the insanity with non-replaceable batteries.

A user-replaceable battery is almost like a battery that never dies. No effort wasted with tedious "battery care". No worries about weardown from high usage. Just enjoying using the device.
